A friend is building a house on his farm (40 acres). The permits for this rural home is over $1000 and they are demanding that he provide a Lic. number for the plumber and the electrician. They are going to do their own electrical work because he did that for years but isn't licensed anymore. Been a hassle. Now they tell him that he will have to dig a hole, line it with plastic and when they pour the footings and sidewalks, they will have to wash out the concrete trucks into this pit...they claim it is the EPA making them do it [the debil made me do it] I am really curious how and why would you need to fret over cement as a "toxic" substance and you would somehow improve the situation by putting a poly hydrocarbon in a hole and placing the cement there and covering it up..The cure seems worse than the disease.
